Application filed March 3, 1922. Serial No. 540,767.

To all whom it may concern:

Be it known that I, FRED 1L. HoRNING, a citizen of the United States,residing at Schuylkill Haven, in the county of Schuylkill, State ofPennsylvania, have invented certain new' and useful Improvements inSupports for Pressure-Retaining Valves, of which the following is adescription, reference being had to the accompanying drawing and to thefigures of reference marked thereon. n

This invention relates. to supports, and more particularly to a bracketor support for a pressure retaining valve.

In railway practice the triple valve exhaust of, the standardfreight carbrake cylinder and auxiliary reservoir combined is connected by means ofa small length of pipe to the usual weight or spring type'of pressureretaining valve. At the present time the pressure retaining valve isfastened to the car by bolts or wood screws which pass throughperforations in ears or lugs integral with the valve It is frequentlynecessary to remove these pressure retaining valves for repairs andreplacements. Much difficult has been encountered in the quick and facie removal of these valves as generally the bolts or screws have to becut offand in many instances the valves have become broken in thusdetaching them from the car.

The object of the present invention is to,

provide a simple, cheap device for firmly holding the pressure retainingvalve in its connected position while permitting, its ready removaland'assembly.

Another object of this invention resides in the provision of a simplesheet metal sup-- port forthedpurpose set forth, which isconstructed anarranged to efi'e'ctively hold the valve in posit'on on the car.

These and Otl'lfili objects will be apparent from. a perusal o thefollowing specificati'on when taken in connection with the accompanyingdrawin s, wherein Fi ure 1 is an e evation of a standard freig t carbrake cylinder and auxiliary reservoir combined showing the triple valveand pipe connection to the pressure retaining valve illustrated as heldby my improved supporting device;

stituting a rear wall main portion and are perspective view of thesupportusual type of sprlng or weight operated pressure retaining valve4, which, as is well known, is provided with the opposed ears or lugs 5and 6 perforatedto receive the customary fastening bolts or screws. llnthe standard practice this pressure retaining valve at is attached tothe pipe 3 by means of a7 threaded connection and a fastening nutHeretofore these valves 4 have been attached to the car by means ofbolts or screws passing through the perforations in the ears 5 and 6,but such a manner of fastening has proven exceedingly objectionablebecause it has been; necessary in many instances to cut the bolts andscrews in order to free the valveparticularly when the screws havebecome rusty or the threads worn. In many cases the valves have becomebroken in so removing them. i

In the present instance all these objections are overcome by a simplesupport for detachablyholding the valve 4: in position 011' comprises asin le the car. The support sheet metal piece formed or bent into t 'eshape of a bracket or support. This sheet metal piece comprises a mainportion 8 conand suitably perforated, as at 9, for attachment to the carwall by screws or bolts. This main portion is provided with a pluralityof integral flaps or extensions WhlOh in the preferred embodiment of theinvention are cut to the form and folded, as is illustrated in Fig. '2.As there shown, each end of this main portion is provided with pairs ofextensions 11, 12,

13 and 14: projecting laterally therefrom.

are bent upwardly at right angles to the tering holes 15, 16, 17 and 18to receive fastening cotter pins 19 and 20. Preferably, each end of themain portion is likewise provided with an end flap 21 and 22 which foldTn the finished device, these pairs of ears provided with regisissecurely locked in position between the pairs of ears, 11, 12, 13 and 14to close the ends of the support. These end fia s are not essential, butare desired.

' clearly illustrated in Fig. 1, the lateral lugs 5 and 6 of the valvelie within the upbent side flaps 11, 12, 13 and 14 and are held in suchposition by the cotter pins 19 and 20. In this position the largecylinder 4' of the valve projects across the central transverse axis ofthe main portion and the inner walls of the side flaps 11 and 13 arespaced apart therefrom to accommodate this increased size of the valve.So, also, the transverse axis 4 of the valve projects between the flaps12 and 14, the inner walls of which are cut, as illustrated, to conformto the contour of the valve at this point. As shown, each inner wall ofthe flaps 12 and 14 are provided with a shoulder 23 and 24 to form aseat 25 adapted to snugly hold the transverse axis 4" of the valve fromlateral play. This shoulder is also provided so that the same supportwill snugly retain either a spring type valve or a weight tyfpe valve inposition, since these valves are 0 slightly different shape at thisportion and are of slightly different diameter. With this constructionwhen the valve is placed in position and the cotter pins 19 and 20passed through the holes 15, 16, 17 and 18, the valve and cannot rattleor become inadvertentl displaced. The valve is quickly remove by takinout the cotter pins and is then unscrewe from the pipe.

It is manlfest that the support is capable of many modifications indesign according to the type of valve to be held and therefore theinvention is not to be restricted to the exact details of constructionexcept in so far as the are limited by the scope of the appende claimsas interpretedb the prior art.

Having thus described t e invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A sheet metal support for a pressure retaining valve comprising amain portion having means for attachment to a car, said main portionhaving integral "flaps constructed and arranged to receive theperforated attaching ears of the valve therebetween, and means forholding said ears in such osition.

2. sheet metal support for a pressure retaining valve comprising a mainportion adapted for attachment to a car, said main portion having pairsof flaps at each end adapted to receive the body of the valvetherebetween, said pairs of flaps being spaced apart to receive theperforated attaching ears of the valve therebetween, said pairs of flapshaving registering apertures, and cotter pins detachably passlngtherethrough to hold said valve in position.

3. A sheet metal support for a pressure retaining valve com rlsing amain portion suitably perforated or attachment to a car, said mainportion havin integral-flaps at each end thereof spaced for the centraltransverse axis of the main portion to permit the passing of the valvebody between said flaps, said pairs of flaps being spaced apart toreceive the attachin ears of the valve therebetween, and provi ed withregistering holes for the reception of cotter pins for detachablyfastening said valve in said support.

In testimony whereof, I afiix my signature.

FRED L. HORNING.
